COMPARATORS

1. AZ393 Low Power Comparator — DIP-8

The AZ393/393C series consists of two independent precision voltage comparators with an offset voltage specification as low as 1mV. The input common mode voltage range of these comparators includes ground, even when operated from a single power supply voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. 10 pages.

The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. 19 pages.

3. LM193/LM293/LM393 Low Power Comparator — ST

4. LM193-393 — National Semiconductor

The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. 14 pages.

5. LM311 Single Comparator

A monolithic, low input current voltage comparator. The device is also designed to operate from dual or single supply voltage. 10 pages.

6. LM339 Quad Comparator — Fujitsu

A Quad Comparator which consists of four independent channels. The MB4204 is designed to operate form either a single power or dual power supplies over a wide range of voltages. The input characteristics is equivalent of current industry standard comparator. 8 pages.

7. LM339 Quad Comparator — Texas Instruments

These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wire-AND relationships. 8 pages.
